add more digits on the Mobile Number field

[mbismillah]

Hi
As I am a complete beginner to Access I am stuck with the Mobile Number Field. I am trying to add more digits to this filed but it is coming up with an error.

Hi. Welcome to AWF!

What was the error message? What is the field size in the table? Can you adjust it there?

And you cannot say what that error is?
